Oil Pressure Gauge for Fuel Pressure

[YoMommaWoo]

Is anyone using an electrical oil pressure gauge to monitor fuel pressure? How accurate are the readings?

Also could someone explain to me why the electrical f/p gauges are so much more expensive than the electrical oil pressure gauges?

I use a Greddy oil pressure guage for fuel pressure... the sending unit is the same, just a diferent guage... it works fine, seems accurate, and reads to 10bar so I know what my fuel pressure is exactly, not a guess... it makes tuning the fuel curve with the cartech fmu easier.. I run 130 psi fuel pressure and the guage is a must!
